If "2 power" means 'squared' then the answers are:
1. (t-5)^2 = 0
t = 5
2. (y+3)^2 = 0
y = -3
3. (2x+4)^2 = 0
=> 2x+4 = 0
=> 2x = -4
=> x = -2.

Question 1
(t - 5)² = 0
t = 5
Question 2
(y + 3)² = 0
y = - 3
Question 3
4x² + 16x + 16 = 0
x² + 4x + 4 = 0
(x + 2).(x + 2) = 0
x = - 2

(t - 5)² = 0
FOIL
(t - 5)(t - 5) = 0
t² - 5t - 5t + 25 = 0
t² - 10t + 25 = 0
